bundling up tokyo tourist spots for efficiency

Hi there!

I don't know if you will be able to see all these places in 4 days. For instance the Ghibli museum and Odaiba can pretty much take up a full day or at minimum half a day.

A couple of places you could combine are:
odaiba-tokyo man made island, beach/liberty statue, toyota mega web showroom and the miraikan nat'l museum of emerging sci and innovation, as these are all located in the Odaiba area.

The rest of the places are all spread throughout Tokyo so I would recommend making a list of what you wish to visit most and visit them in that order.

Have a great time in Japan!
